Abstract
This study includes two selected groups of patients operated for cataract with implantation of either a polymetacrylate (PMMA, Sinskey J-loop, prolene haptics, Mod.102H, Pharmacia) or a soft hydrogel (IO-gel, Alcon) posterior chamber lens. There were 27 patients in the PMMA group and 32 in the hydrogel lens group. The study concludes that after 1 year of observation a comparison between the two groups disclosed no major difference concerning the visual outcome and influence on the ocular tissue. No substantial observations point towards the hydrogel lens as the more biocompatible of the two lenses.
